Hi, I have been playing minecraft (ver 1.5.2) for a few weeks now and a friend told me about mods.
So I downloaded winrar and forge (downloaded from minecraftforge.net/forums).
I chose version 7.8.1.738 for minecraft 1.5.2. I opened minecraft.jar and deleted the meta-inf folder and then copied everything out of the forge download into the minecraft.jar file. I closed the minecraft.jar file and then tried to restart the game. It had a new little window that popped up titled Hello. FML is setting up your minecraft environment. It did some loading things and then a new window opened that states: There was a fatal error starting up minecraft and FML Minecraft cannot launch in it's current configuration. I consulted the file that it specified and this is what it shows:

Have I done something wrong? How do I fix this?
I have searched these forums and read all of the threads that seemed to be similar to what is happening with me but I see nothing that is the same. In one of the other threads someone mentioned adding code chicken core or something like that but after adding forge to minecraft.jar. Do I need to add that first and were would I download that from?
Thank you for looking at this.
backup your .minecraft folder to your desktop, then with the one you still have in %appdata% go back into the minecraft.jar for forge and then wipe it. then force update it back to 1.5.2. then get the installer and install it (or just reinstall it)
I did what you said and I can now start Minecraft without forge, thanks! I tried reloading forge with a bunch of different versions, all listed for 1.5.2, I tried 7.8.0.684, 697, 700, 705, 725, 726, 736, 737 and 738. All come up with the same errors in the start log as listed above.
This line: 2013-09-18 22:30:42 [INFO] [STDERR] Exception in thread "Thread-2" java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/google/common/collect/Multimap seems to be the start of the problem with all of the loaders in question, what could be wrong in it?
Edit: I should also add that there are no files in my coremods and mods folders in my .minecraft folder.
In one of the other threads that I read said to download MultMC. They stated that you can load forge with that with the touch of one of its magic buttons. I downloaded it and I don't see any buttons for downloading forge with it. Any help with this?
try using a skydaz installer, like nei. it will install the mod with forge and you can just take out the mod but get it for 1.5.2 or what ever the version is
So I downloaded winrar and forge (downloaded from minecraftforge.net/forums).
I chose version 7.8.1.738 for minecraft 1.5.2. I opened minecraft.jar and deleted the meta-inf folder and then copied everything out of the forge download into the minecraft.jar file. I closed the minecraft.jar file and then tried to restart the game. It had a new little window that popped up titled Hello. FML is setting up your minecraft environment. It did some loading things and then a new window opened that states: There was a fatal error starting up minecraft and FML Minecraft cannot launch in it's current configuration.

Have I done something wrong? How do I fix this?
I have searched these forums and read all of the threads that seemed to be similar to what is happening with me but I see nothing that is the same. In one of the other threads someone mentioned adding code chicken core or something like that but after adding forge to minecraft.jar. Do I need to add that first and were would I download that from?
Thank you for looking at this.

Edit: I should also add that there are no files in my coremods and mods folders in my .minecraft folder.
p.s. what i said will not work with multimc
